Pet sometimes lose their trait in certain scenarios

It happens randomly, but most of the time it seems the first one(automatically assigned by CAP when you click the race).

In CAP:

"A - None - None", which "A" is automatically assigned by CAP's race

1) I changed it to:

"A - B - C"

Then:

"A - B - C".

2) If I changed it to:

"D - B - E"

Then:

"D - B - E"

or "A - B - E"

or "A - E"

or "A - B".

You're right - changing a trait of already-created pet may be related to the link you provided.

But this issue sometimes happened on new pets. Randomly.

> they still show the traits in the relationship panel ?

If the pet have 2 traits, then the relationship panel show only 2.
